WM. TAYLOR, OF BERLIN, NEW YORK.

BOOT-CRIME.

Specification of Letters Patent No. 4,798, dated. October 3, 1846.

To all whom t may concern:

Be it known that I, WILLIAM TAYLOR, of Berlin, in the county ofRensselaer and State of New York, have invented. a new and ImprovedCrimping-Tool for Crimping Boots; and I do hereby declare that thefollowing is a full, clear, and eXact description of the same, referencebeing had to the accompanying drawings, making part of thisspecification, in which- Figures l and 2, are views of one of mytools,*the former representing the jaws closed, and the latter open,with the crimp placed in the position which it occupies at the time ofcommencing the operation of crimping.

The nature of my invention consists in causing the leather to conform tothe lshape of the crimp, by forcing the latter, after the leather hasbeen applied thereto, between two smooth, iron jaws, of peculiarshape,-the interval between said jaws be-v ing regulated by a screw ;-asecond screw acting against the heel of the crimp, and serving to thrustthe instep thereof, and the parts adjacent thereto-, between the jaws asbefore mentioned.

The same letters refer to the same parts in both the figures.

a a, a a, are the jaws, (of the 4shape represented in Fig. 2,)-irmlyriveted to the bars b Z) and c e. The upper bar Z) b, is joined to thecrosshead cl, by a hinge at c;- so that it may be thro-wn back as shownin Fig. 2. f is a screw passing through a slot in the upper bar, andworking in the lower, near the end thereof. It serves to regulate theinterval between the jaws. lower attached lto the point of the screw j,in such a manner as not to prevent' the revolution of the latter. Theends of this follower are notched or forked over the bars b and o c,which serve as guides thereto. The notch la., adjacent to the hinged barZ) is Lmade the deepest, to allow the necessary movement of this bar. i,is a crank or winch, attached to the screw j,

g is a folwhich gives motion to the follower g. ,7c lo, are two pinsprojecting from the follower, and serving to support the heel of thecrimp. The whole instrument is intended to be made of iron. The edges ZZ, Z l, &c. of the jaws a a, cz a, are rounded olf to prevent theirabraiding the leather.

The operation is as follows: The leather having been cut to the propershape, and soaked in water as usual,-is applied to the crimp. The upperbar Z) 7), being turned. back, (as shown in Fig. 2) and the followerwithdrawn as far as necessary,-'the heel of the crimp, which is notchedas shown at m to fit the follower,-is laid upon the pins 7c lef-theinstep at the same time resting upon the lower jaw. 'Ihe upper bar b bis then turned down to the position shown in Fig. l, and by means of thescrew f, the jaws are brought to the proper distance apart. The screw j,being then put in motion by 'the crank ,-the crimp with the leatherthereon, is forced forward between the jaws with such a degree offriction as serves to cause the lat-ter to be drawn tightly over thefo-rmer, and to conform exactly to the shape thereof. While the severalparts are in this position, the leather is tacked at its edges to thecrimp ,-after which the screw f being slacked,-the upper bar b b isturned back and the work removed, and set to dry, as usual.

What I claim as my invention and. desire to secure by Letters Patent isThe combination of the adjustable metallic jaws attached to the ironbars connected with the cross head, with the follower actuated by ascrew passing through the crosshead, and serving to thrust the crimpwith the leather thereon, between said jaws; the whole forming ahand-tool, and being constructed and operating substantially as hereindescribed.
